Application filed March 18,1914. Serial No. 825,456.

an acetylene miners lamp having an ignit ing device which can be easily removed for adjustment and repair and can also be securely and firmly locked in proper position when required for use. r I

The following is a description of an embodimentof my invention, reference being had to the accompanying drawings, in wh1ch,

Figure 1 shows a front elevation of a lamp embodying my' invention, with the burner tip om1tted. F g. 2 shows aside elevation of the same lamp partly in section. Fig.3 shows a front elevation of the reflector. Fig. 4 shows a detail of the reflector. Fig. 5 shows details of the igniting device. Fig. 6 shows other details of the igniting device. Figs. 7 and 8 show details of the bearing and wheel.

Referring more particularly to the drawings, A is alamp-body having an outlet and burner tube 1 projecting laterally from the sidethereof and a reflector-support 3 forming part of the lamp-body. A reflector 4: carries an internally screw-threaded bushing 4' which screws onto the burner tube 1 so that the reflector is carried thereby. Surrounding the burner tube 1 and inside the reflector-support 3 is a movable socket 5 attached to which is a screw-threaded pin or base 6 on which is screwed the outer portion of the igniting device. The igniting device consists of the socket 5, the pin or base 6, a bearing 7 having internal screwthreads engaging the screw-threads-upon the base 6, a friction wheel 8, a piece of spark: ing'material 9, preferably what is commercially known as Auermetall, and the spring 10 which forces the sparking material against the wheel, the sparking material and spring being inside the bearing. The bearing 7 passes through the'reflector at the hole 11 and is flattened on the side 74 which contacts with the reflector-support '3 so as to be held thereby from turning.

The hole 11 in the reflector is such that its upper-edge presses upon theibearing of the igniter so as tomaintain the flat side of the bearing against the edge of thereflectorsupport, thus locking the bearing in posi tion and preventing it, from turning. The support 3 has some resiliency in the inwardly extending portion 12'betwee'n its base and the outer ring 18. and the reflector 4 being of thin metal is also resilient T he resiliency of one or both of these parts permits the reflector after it has been screwed on the burner tube sufficiently to engage the burner support to be further turned'u ntil the igniter wheel 8 is'brought' below the burner tube which is the most desirable position for it.

In assembling the parts, the pin or'base 6 is projected through the hole 11 in the reflector and the bearing"? carrying thefriction wheel 8, sparking material9 and internal spring 10 isscrewed thereon until the spark ng material is forced by the pin 6 into sufficiently intimate contact with the friction wheel 8. The socket 5 is then placed 'over the collar or bushingt' carried by the reflector and the reflector is screwed upon the burner tube 1, care being taken that the flat side 7 of the bearing, which is parallel to the axis of the friction wheel 8,

is brought into engagement with the outer rim of the reflector-support 3. The reflector is then turned until it firmlv engages the reflector-support and the ignition device is brought below the burner tube, the resiliencv heretofore referred to permitting this exact adjustm nt. The burner tip 14: is then pla ed upon the burner tube 1. j

The igniting device eing carried by the burner tube and the reflector-support. which form parts of the lamp-bodv. is firmlv held in position without being carried bv the reflector -which serves simply to maintain it against turning. so that when it is placed in such a position that the burner tube lics in the plane of the frictionwheel, it will be locked in that position. In my preferred form, the bearing :of the igniting device is made triangular in cross-section. since drawn brass wire of that shapeand of the proper size can be obtained so as to make it unnecessarv to machine the bearing for the purpose of obtaining the flat locking si-"le" thereon. Except'for thisadvantage in (10- mg away with a certain amount of machining, the 'shape of the bearing is unimportantso long as it has a flat side properly related to the plane of th friction wheel.

lhe friction wheel is provided with teeth in the ordinary manner which should at tack the sparking material when the wheel 'is rotated in a counter-clockwise direction show 11 by the arrow in Fig. 2.

When constructed as above described, the

base of the igniter being anchored by the flector and the lamp-body and so does not interfere with the angular adjustment of the ignition device, which is permitted by the flexibility of the reflector and support. ,As will be evident to those skilled in the art, my invention permitsof various modifications Without departing from the spirit thereof or the scope of the appended claims.

What I claim is:

1. In an acetylene gas generating lamp, I
